Although it is the biggest time-waster in office life, you must never underrate the importance of the memo. You will be judged by the volume of your paper work.
The memo's chief function ... is as a track-coverer, so that you can turn on someone six months later and snarl: 'Well, you should have known about it, I sent you a memo.
The letter of application ... should be a masterpiece of fiction, papering over all the cracks. Get it properly typed on decent writing paper. Never let it run over the page, people get bored with reading.
Go to lots of interviews, at least one a month even when you don't need a job, to keep in training for when you do.
Always be nice to everyone in the firm on the way up. You never know who you may meet on the way down.
